Both police and Waymo confirmed Saturday that the self-driving van had been in manual mode with an operator behind the wheel at the time of the crash. Chandler police initially said Friday the car had been operating in autonomous mode.

The silver Honda sedan was traveling eastbound on Chandler Boulevard toward the Los Feliz Drive intersection when the traffic light changed from yellow to red, Detective Seth Tyler of the Chandler police said.

The driver, who police have not yet named, continued to drive into the intersection despite the light having turned red, Tyler said. Another vehicle began to drive northbound on a green light while the Honda was passing through the intersection.

The Honda then swerved to avoid colliding with the car before it drove over the raised median and into the westbound lanes, police said. The Honda hit the Waymo white Chrysler minivan, which had been slowing for the red light at Los Feliz Drive.

Investigators later determined the Honda had been traveling at about 40 mph when the car entered the intersection. Tyler said the driver was cited for a red-light violation on Saturday.

"At 40 mph, this places the Honda approximately 180 feet behind the intersection when the light cycled to red," Tyler said.

The Waymo operator required hospitalization because of their injuries, Tyler said. Both vehicles had to be towed from the scene because of the damage from the collision.
